To all whom may concern Be .it known thatI,"O

citizen of' the UnitedStates, residing at Halliday, in the county-ofDunn and State 5 of North Dakota, have inventedcertain new and usefullmprovements`'inv Grain-Spout Doors, of which the following''is aspecifiv cation', reference being hadfto the accompanying drawings.4This invention relates .to the grain spouts of elevators andlikestructures, and particv ularlyl to means disposed in the length ofthe spout and adjacent 'its relatively small delivery end whereby accessmay be had to the interiorof the spout; f 1

In the grain spouts 'ofl,elevators as ordinarily constructed, there is'great trouble with the spout becoming clogged with stones, horseshoes,wooden blocks,`hay and straw,I and like foreign articles gettingwithin'the spout at its lOlYI or discharge end and blocking the spout,these articles `not being able to lpass through the small Aend of thespout.- It .is very difficult-'to remove these articles 'and the onlyway it can be vdone in spouts as'- at'fpresent constructed is to removethey articlesthrough a hole in the bin to which the spoutis connected,fishing `for these articles'lhaving' tobe done through the entire lengthlof the spout. lThis ordinarily takes from thirty minutes7 toan A Thegeneral do away with'this inconvenience by .providing a'door disposed inthe spout adjacent its narrow or delivery end, and further to soconstruct the door that' it will:` not impede the Vpassage of thematerial passing through the spout and will not be liable .to catch andretain any of this material.

A further object of the invention is the provision of a door having animproved l 45 form of latching device whereby the door is held in place,this latching device also constituting a handle for the door.

Other objects will appear in the course of l. the following description.

50, My invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a grain l distributing spout providedwith my nnproved of the spout, the door being also shown in section;Fig. 3 is a transverse secthrough this hole in -the b in downward objectoflfiny invention is to door; Fig; 2 is a longitudinal sec-1 tional viewof the spout, the door and the keeper being'alsoshown partly in sectionsFig.' 4 is a lperspective detail view of the comb-ined latch and handle;Fig. 5r isl a per-A spective View ofthe door, detached.

Referring to these drawings, 10 designatesv a vspout leading from a bin11. This spout as illustrated is rotatably connected with the b1n11 sothat it may be rotated around its axis to discharge into Iany one of anumber of hoppers leading toother chutes-or spouts lnfth'e manner common1n grain elevators.'

A djacent its delivery end the spout is proi. vlded with an opening,designated 12, which' is relatively long and hasy a width v'eryj'vnearly equal the ldoor ofthe spout. This opening, however, may be madeof any suit-` able length or width. Disposed uponl the, 1

exterior of the spout, at thesmaller end of and has its body outwardlydisplaced from ns the opening, is a keeper plate-13 which-is vriveted orotherwise attached to the spout the plane of the' face'of the spout soas to l form a pocket extending below the opening 12 and beyond the sidewalls of the opening. Disposed above the upper end, of fthe,

opening is a strapfll, forming a latch keeper. v v v The' door .consistsof aplate 15 which is transversely curved .to itthe curvature of thespout, and which,rif the spout is tapered,

is likewisereduced in -width at its lower end,

the-lower extremity of vthis :door being.,y

adapted tobe inserted in the pocket-formed by the strap 14. Adjacent theupper edge' lof the door there is provided a guide strap 16. Mountedupon the door is the handle 17 which isjformed of astrip yof resilientmetal riveted aty its lower end to thedoor,

as at 19, -and'having its' upperend extended v4through the strap 16 andnormally extended v,beyond the upper edge ofthe door. v This re silientstrip is preferablyv longitudinally 4slotted at 20 just above theintermediate .bowed portion. of the spring strip for the passage ofI astud 21 which passesthrough the .strap 16. The resilient strip, asbefore stated, is bowed, this bowed portion extending between the strap16 and the lower end of the strip. l i y Normally, and when the door isin place, the lower edge ofthe door is disposedin a pocket 13 and theupper'end of the resilient handle is disposed in the strap 14. When itis desired to remove the door, the spring handlevis compressed or;contracted, thus ,'Furtherniore, vit will be seen that the innervlWithdrawing the latching end of the handle fromitsengagement with thestrap 14 and the door then may be readily lifted out from the pocket.The door maybe as readily put in place and when in place will be rigidlyheld by the latching end of the handle.

lt will be seen that with this. construction it is" always easy toobtain' access to the lower end of the spout so Aas to remove therefromAany foreign artic-ies which -have lodged there,4 no matter how .largethis may be.

aee of the spout is entirely 'smooth as the only .projections arenileheads ofthe rivets Winch vhold the straps in glace Wha@ i have aus-aereaa @wenn definite.

construction for this door which I'believe -to 'be particularlyeffective, it will ofcourse -be understood that the door may be variedin some respects Without departing from lthe, spirit of the inventionand'that the latch# ing device ot the door may be changed. The: door isparticularly adaptedto" the grain distributing spout ofl elevatorsthough not 4necessarily limitedto this use.
